Characterization of microbial assemblages on micro-plastics in a river system
(North-West University (South Africa), 2021)Microplastics as pollutants originate from land-based sources and are persistent and ubiquitous in the aquatic environment. The risks posed by microplastics as vectors and habitats for potentially harmful microbial groups ... -
Characterization of Microbial Survivall in the Presence of Radioactive 14C Spiked Salts in Order to Minimize W,aste from Graphite Moderated Nuclear Reactors
(North-West University (South Africa), 2018)The Pebble Bed Modular Reactor (PBMR) is a high temperature, Gas (HTG) (helium) cooled reactor, which uses graphite as a moderator and a neutrons reflector. During the reactors operation, graphite is irradiated and ... -
Characterization of mtDNA variation in a cohort of South African paediatric patients with mitochondrial disease
(Springer Nature, 2012)Mitochondrial disease can be attributed to both mitochondrial and nuclear gene mutations. It has a heterogeneous clinical and biochemical profile, which is compounded by the diversity of the genetic background. Disease-based ... -
Characterization of NaA-zeolite membranes using pervaporation
(North-West University, 2005)Pervaporation has gained increasing attention as an energy saving process for separating azeotropes such as ethanol and water mixtures. Pervaporation distinguishes itself from other membrane processes in that it entails ... -
Characterization of personal solar ultraviolet radiation exposure using detrended fluctuation analysis
(Elsevier, 2020)Studies of personal solar ultraviolet radiation (pUVR) exposure are important to identify populations at-risk of excess and insufficient exposure given the negative and positive health impacts, respectively, of time spent ... -
Characterization of plasmids associated with antibiotic resistant bacteria in the North-West Province
(North-West University, 2016)Antibiotic release in natural environments select for antibiotic resistant bacteria. These antibiotic resistant bacteria are in many cases associated with plasmids, containing one or more resistant genes. Plasmids are ... -
Characterization of polymorph transformations that decrease the stability of tablets containing the who essential drug mebendazole
(Elsevier, 2010)This study investigated the influence of moisture and heat on the stability of mebendazole polymorph C in tablets. The polymorphic forms of mebendazole display significant differences in solubility and therapeutic efficacy ... -
Characterization of rare earth elements by XRT sorting products of a South African coal seam
(Taylor & Francis, 2019)South Africa is an important participant in the global coal market. The four Upper coal seam situated in Springs-Witbank Coalfield was subjected to XRT sorting and subsequent mineralogical studies to characterize REE ... -
Characterization of Rhizobacteria from Field Grown Genetically Modified (GM) and Non–GM Maizes
(SciELO, 2014)This study was done to examine the rhizobacteria from field grown Genetically Modified (GM) maize and its non-GM counterpart. Rhizospheric soil samples were collected at 30 days after sowing (DAS) and at post-harvest from ... -
Characterization of satellite-based proxies for estimating nucleation mode particles over South Africa
(EGU, 2015)Proxies for estimating nucleation mode number concentrations and further simplification for their use with satellite data have been presented in Kulmala et al. (2011). In this paper we discuss the underlying assumptions ... -
Characterization of solid lipid dispersions prepared by hot fusion containing a double-fixed dose combination of artemether and lumefantrine
(Taylor & Francis, 2020)bjective The World Health Organization has called for the development of novel drug delivery systems to combat malaria – the fourth most prevalent cause of death globally. The plausibility of utilizing hot fusion to prepare ... -
Characterization of spatial resolution through Fourier ring correlation in digital neutron radiography
(North-West University (South Africa), 2020)Spatial resolution is a very important parameter in any imaging system, from medical to industrial even in astronomy and it should be considered every time images are analysed or even before processing. The aim of this ... -
Characterization of species differences in xenobiotic metabolism in non-experimental animals
(Pharmaceutical Society of Japan, 2017)The ability to metabolize xenobiotics in organisms has a wide degree of variation among organisms. This is caused by differences in the pattern of xenobiotic bioaccumulation among organisms, which affects their tolerance. ... -
Characterization of Staphylococcus aureus from Nigeria and South Africa
(North-West University (South Africa), 2020)The detection of methicillin-resistant Staphylococcus aureus (MRSA) in wastewater system from clinical sources has posed a public health challenge in many countries worldwide. Of a greater concern is the discharge of ... -
Characterization of tabanid flies (Diptera: Tabanidae) in South Africa and Zambia and detection of protozoan parasites they are harbouring
(Cambridge Open, 2017)Tabanids are haematophagous flies feeding on livestock and wildlife. In the absence of information on the relationship of tabanid flies and protozoan parasites in South Africa and Zambia, the current study was aimed at ... -
Characterization of the cell-free DNA released by cultured cancer cells
(Elsevier, 2016)The most prominent factor that delays the translation of cell-free DNA (cfDNA) analyses to clinical practice is the lack of knowledge regarding its origin and composition. The elucidation of the former is complicated by ... -
Characterization of the enzyme activity and substrate specificity of GLYAT haplotypes
(North-West University (South Africa), 2020)The unavoidable exposure to xenobiotics makes detoxification a necessity. Detoxification is not just one reaction but four reactions (Phase 0, I, II and III) that work together. The glycine conjugation pathway is one of ... -
Characterization of the flow and compression properties of chitosan
(North-West University, 2008)The most useful dosage form taken from a patient's point of view is tablets because of its simplicity and portability (Takeuchi et al., 2004:132). Manufacturing of tablets can be done by wet granulation or direct compression ... -
The characterization of the severity of rotor delevitation events: a parametric study
(s.n, 2012)Active magnetic bearing (AMB) failure and the ensuing rotor behavior is a very important aspect of AMB safety. A model for this rotor behavior was developed and was used to characterize the severity of rotor delevitation ... -
Characterization of wheat nematodes from cultivars in South Africa
(North-West University (South Africa), 2020)Plant-parasitic nematodes (PPNs) naturally live in soil and attack small roots, but some species inhabit and feed in bulbs, buds, stems, leaves, or flowers. This leads to plant weakness and they often appear to suffer from ...
